Abstract
This paper shows the effect of different modes of laser treatment on the final structure of the coating obtained by the CS method. Among the studied modes, the following were selected: the speed of movement of the laser spot, defocused or focused laser beam, continuous or pulsed mode of laser treatment. The CS coatings of systems Ni, Ni-Ti, Al have been investigated. It is shown that under pulsed and defocused modes, the resulting coatings have cracks and other types of defects. It is also shown that the microhardness of CS coatings after laser treatment with a laser beam increases: 8 times for the Al system, 3 times for the Ni-Ti system, and does not increase for the Ni system.
